Enameled wire is a main type of winding group, mainly composed of a conductor and an insulating layer, and can be applied to electronic devices such as winding inductors, transformers, and motor windings.
[0003] Both the plastic-coated copper bar and the enameled wire have pin structures. After the product is manufactured, it is often necessary to detect the height and position of the pins to determine whether the height and position of the pins meet the design requirements. Currently, the detection of pins is generally carried out manually using measuring tools such as plug gauges one by one, with low detection efficiency, long time consumption, and difficulty in detecting the position of the pins. At the same time, plug gauges also have problems such as high manufacturing cost, short service life, and easy generation of measurement errors after wear.

[0029] Embodiment
[0030] This embodiment provides a fixture for detecting the height and position of pins of an electrical connection device. The electrical connection device can be an electrical connection device with pins such as a plastic-coated copper bar or an enameled wire. This embodiment takes the plastic-coated copper bar as an example. Please refer to Figures 1-4 , the fixture for detecting the height and position of pins of the electrical connection device includes: a bottom plate 1. The bottom plate 1 is used to fix the electrical connection device 2 when detecting the height and position of the pins. The electrical connection device 2 has a standard specification. According to its standard specification, the bottom plate 1 is provided with a mounting groove 101 adapted to the shape and size of the electrical connection device 2. In this embodiment, as Figure 1 shown, the electrical connection device 2 is a plastic-coated copper bar, and its side has a plurality of pins 201. When the electrical connection device 2 is adaptively placed in the mounting groove 101, the pins 201 protrude outside the mounting groove 101. To realize the detection of the height and position of the pins 201, the detection fixture further includes a detection member 3. The detection member 3 is detachably connected to the bottom plate 1. The detection member 3 is arranged corresponding to the position of the pins 201 one by one. The detection member 3 is provided with a detection hole 301, and the detection hole 301 is a stepped hole.
[0031] For the fixture for detecting the height and position of pins of the electrical connection device provided in this embodiment, during use, the electrical connection device 2 is adaptively fixed and placed in the mounting groove 101. The pins of the electrical connection device 2 protrude from the top surface of the mounting groove 101. The detection member 3 is inserted into the bottom plate 1. Since the position and size of the detection hole 301 are set according to the standard specification of the electrical connection device 2, if the detection member 3 can be smoothly pushed and inserted into the bottom plate 1, that is, at this time, the pins 201 of the electrical connection device 2 are smoothly inserted into the detection hole 301, it means that the position of the pins 201 meets the design requirements. At the same time, it can also be judged that the flatness of the surface of the pins 201 meets the requirements; if the detection member 3 cannot be smoothly inserted into the bottom plate 1, it means that the position of the pins 201 does not meet the design requirements. When the pins 201 are inserted into the detection hole 301, since the detection hole 301 is set as a stepped hole, it can be judged whether the height of the pins 201 meets the design requirements by detecting whether the top surface of the pins 201 protrudes from the upper surface of the stepped hole or is lower than the surface of the bottom step of the stepped hole. The detection fixture provided in this embodiment has a simple structure and is easy to operate for detection. Only by inserting the detection member 3 can the detection of the position and height of the pins 201 be completed at the same time. The detection efficiency is high and the error is small. The cost of the fixture is low, and it can be widely used in the field of detecting the height and position of pins of electrical connection devices.
[0032] To accurately detect the height of the pins 201, in the detection fixture provided in this embodiment, the stepped hole is realized by the following structure: as Figure 4As shown in the figure, the detection component 3 includes a detection component body 302. The cross-sectional shape of the detection component body 302 is approximately rectangular. One end of the detection component body 302 is provided with a detection hole 301. One end of the detection component body 302 close to the detection hole 301 includes a stepped portion, and the stepped portion is arranged on the outer periphery of the detection hole 301, so that the top surface on one side of the detection hole 301 is higher than the top surface on the other side, forming a structure of a stepped hole. Specifically, the stepped portion includes a first detection plane 303 and a second detection plane 304 arranged parallel to the first detection plane 303, and the first detection plane 303 is lower than the second detection plane 304, so that the top surfaces on both sides of the detection hole 301 have different heights respectively. Thus, it can be judged whether the height of the pin 201 meets the design requirements by detecting whether the detection pin 201 is lower than the first detection plane 303 or higher than the second detection plane 304. This detection method is simple and easy to operate and the result is accurate.
[0033] To realize the efficient insertion of the detection component 3 into the bottom plate 1 to quickly detect the height and position of the pin 201, a connecting portion 305 is provided at the bottom of the end of the detection component body 302 far from the detection hole 301. A connecting hole 102 adapted to the connecting portion 305 is provided at the corresponding position of the bottom plate 1, and the detection component 3 is detachably connected to the bottom plate through the connecting portion 305 and the connecting hole 102.
[0034] For the convenience of the detection process operation and to realize the quick plugging and unplugging operation of the detection component 3, a handle 4 is further connected to the detection component body 302. The handle 4 is connected to one side of the detection component body 302 close to the connecting portion 305. During detection, the operator inserts the detection component 3 into the bottom plate 1 by holding the handle 4. After the detection is completed, the detection component 3 is pulled out from the connecting hole 102 through the handle 4. The detection process is rapid, time-consuming short, and efficient. For the convenience of viewing the fixture structure, part of the detection component 3 and the handle 4 are shown in the figure.
[0035] To prevent the detection component 3 from scratching or bumping the electrical connection device 2 to be detected during the detection process, a chamfered portion 306 is provided at the end of the detection component body 302 close to the detection hole 301. By chamfering both sides of the end of the detection component body 302, the edge of the detection component body 302 becomes smoother, avoiding damage to the device to be detected.
[0036] A handle member 5 is connected to the top surface of the bottom plate 1. Through the handle member 5, the operator can conveniently carry the detection fixture. For further operation convenience, the handle member 5 is preferably two, and the two handle members are symmetrically arranged on both sides of the top surface of the bottom plate 1.
[0037] In addition, feet 6 are connected to the four corners of the bottom surface of the bottom plate 1. The feet 6 are preferably made of rubber or plastic, which can stably support the bottom plate 1 and prevent scratching the operation table surface.
[0038] Obviously, the above embodiments are merely examples for clear illustration and not limitations on the implementation manners. For those of ordinary skill in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to enumerate all implementation manners here. And the obvious changes or modifications derived therefrom still fall within the protection scope of the creation of the present utility model.
